ABSTRACT:
A system for controlling temperature control elements used to alter temperatures of a liquid comprises a temperature sensor, a first temperature control element, a second temperature control element, and logic. The temperature sensor is configured to sense temperatures of the liquid, and the first and second temperature control elements are each configured to alter a temperature of the liquid. The logic is configured to selectively control, based on the sensed temperatures, activation states of the first and second temperature control elements such that a total activation time associated with the first temperature control element is substantially equal to a total activation time associated with the second temperature control element.
